//! Shared test-context constructors.
//!
//! Almost every crate's test module hand-rolled the same `fn cx() -> Cx`. These
//! are the two canonical shapes that duplication collapsed to (OVERLAP6.16);
//! a test helper routes here with `use sim_kernel::testing::bare_cx as cx;`.

/// Use for tests that exercise structure without driving evaluation.
